摘    要:利用离子交换-电导检测离子色谱法对土壤中有效氟进行测定。选用30 mmol/L氢氧化钾溶液作为淋洗液,流速1.20 mL/min,准确测定有效态(可提取态)氟含量。方法加标回收率为95%~108%,精密度好,检出限低,操作简单,对环境无污染,适合于土壤污染状况的调查。

关 键 词:离子色谱法  有效氟  土壤

Abstract:An ion chromatographic method with ion-exchange and conductivity detection was used to determine available fluorine in soil samples.Using 30 mmol/L of KOH solution as eluent and at flow rate of 1.20 mL/min,the content of available fluorine in sample solution could be determined.The recovery of method for available fluorine was 95%~108%.The method provides the advantages of good precision,lower detection limit,simple operation,environment friendly and can be used in the soil contamination survey.
Keywords:ion chromatography  available fluorine  soil
